[himonkey]

hey guys new to the forum i have a question. Ok me and my friend have a compition against eachother we have a total of 700$ and we must buy a car thats fuel injected we can buy cars for under the price and use the remaining money on spare parts or repairs we cannot trade anything for our cars or get them for free also we must repair them ourselves and heres the catch we can only use 10 tools so thats 10 sizes of sockets/wrenches the test is to see whose car will last the longest from purchase so I need the name of a car that fits this descrition I know its hard but i need some expert advice. thanks guys!
